The resolution the authority approved Wednesday also authorized the acquisition of easements from the program participants who live adjacent to the airport in New Haven and East Haven.

The authority, working with consultant The Jones Payne Group, previously drafted a policies and procedures manual, a homeowner manual, a homeowner participation agreement and deeds of easement, all of which were part of the plan the authority approved Wednesday.

The approval is part of the process the authority must go through in order to apply for the federal funding that will pay most of the cost of doing the work, said Sarah Degutis, an associate with The Jones Payne Group.

The authority previously announced it had selected 10 houses in New Haven and two in East Haven to participate in an $849,582 pilot project to be the first homes soundproofed as part of a broader noise mitigation plan for homes surrounding the airport.

The grant will cover design and engineering work. Construction for work on the first 12 houses will be covered by a separate $660,000 grant, authority Executive Director Tim Larson said

Degutis said her company had acoustically tested 18 homes before choosing the 12 to participate in the pilot program.

Those that did not make the initial 12 are eligible to participate in the broader program that will follow, she said.

As part of the process to prepare for the program, the authority and its consultant has done community outreach to make sure neighbors were fully informed of what happening, Degutis told the authority.

“We just sent a newsletter out a couple of weeks ago,” she said.

In response to a question from authority Chairman John Picard, authority attorney Hugh Manke said the agreements are written so if a contractor does the work and “it doesn’t work,” a homeowner cannot come back to the authority and say, “Do it again.”

Manke also said homeowners aren’t going to be able “to add on to the scope of work,” beyond what’s called for to sound-insulate their houses.

“We’re not going to allow the contractors to take care of your house” in other ways while they’re doing the work, he said.

The 12 homes essentially will be used to cost out a budget for work on a total of 187 homes that were identified in a federally-funded noise mitigation study as affected by airport noise. The homes all fall with a 65-decibel “noise contour” around the airport, officials have said previously.

They were chosen to roughly match the overall distribution of homes that are interested in having work done, which came in as roughly a 5-1 split between New Haven and East Haven, Larson has said.
